We examine the thermal conductivity k and interface thermal conductance G for amorphous and crystalline Zr47Cu31Al13Ni9 alloys in contact with polycrystalline Y2O3. Using time-domain thermoreflectance, we find k=4.5 W m(-1) K-1 for the amorphous metallic alloy of Zr47Cu31Al13Ni9 and k=5.0 W m(-1) K-1 for the crystalline Zr47Cu31Al13Ni9. We also measure G=23 MW m(-2) K-1 for the metallic glass/Y2O3 interface and G=26 MW m(-2) K-1 for the interface between the crystalline Zr47Cu31Al13Ni9 and Y2O3. The thermal conductivity of the crystalline Y2O3 layer is found to be k=5.0 W m(-1) K-1, and the conductances of Al/Y2O3 and Y2O3/Si interfaces are 68 and 45 MW m(-2) K-1, respectively.
